tins for sponge cake

[sweetmonkey]

hi im making a birthday cake for my brothers birthday and have hired a square cake tin but after looking at some of the threads on here everyone has put about dividing the mixture between 2 tins which obviously i would normally do

is it ok if i was to make two batches both with 6oz marg, sr flour and caster sugar and three eggs and then cook one batch at a time but so hopefully that it will fill the tin to the corners

basically is ok to put the mixture in one tin

sorry if this doesnt m ake sense but i have been puking since fri and making a cake is the last thing on my mind but its for my bros 21st

ta

if it is a big tin should be ok. most recipes say how big the tin should be so if the tin is bigger than that it should still rise.

just been and measured and its 8"

thanks!
im off back to bed now
